SPECIFICATION forming part of Letters Patent No. 428,101, dated May 20,1890.

Application filed June 10, 1889. Serial No. 313,663. (No model.)

T0 all whom t may concern.'

Be it known that I, JOHN IRLBACKER, of Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Apparatus for ,Extracting Hops; and I do hereby declare that thefollowing description of my said invention, taken in connection with theaccompanying sheet of drawings, forms a full, clear, and exactspecification, which will enable others skilled in the art to which itappertains to make and use the same.

l My present invention has general reference to improvements inhop-extractors; and it consists in the novel and peculiar combination ofparts and details of construction, as hereinafter first fully set forthand described, and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate my saidinvention more fully, Figure l is a front elevation of my device,showing the saine as connected to the boiling-kettle and extract-cooler.Fig. 2 isa transverse sectional elevation of the extractor. Fig. 3 is avertical central section of the extractor.

Like parts are represented by corresponding letters of reference in allthe figures.

The object of this invention is the production of an efiicient extractorfor the extraction of the iiavors, aromas, and other soluble mattersfrom hops.

To attain thisresult I construct my device as follows:

A in the drawings represents the shell of my device, preferably being ofcylindrical shape, said shell being provided at its lower end with asemi-spherical drum B, being provided with another drum B in itsinterior, said drums being bolted or riveted together, thereby formingan annular chamber or steamspace R within the same, said. chamber Rbeing provided with inlet and outlet passages b h for steam,respectively. From the interior of the drum B leads a pipe I, ashereinafter described, the said drum B being fastened to the shell A bybolts or rivets, as shown in Fig. 1. Near the lower end of the shell Aleads a pipe E for conveying the soluble products of the hops. At themouth of said pipe within the shell A is placed a strainer i" to preventthe hops from entering said pipe.

Nearthe upper end of the said shell leads a pipe .l to convey the wortor water used for leaching the hops. The upper end of the shell A isclosed by a head S, said head being provided at one side with a pipe Z,having branches Z Z, at the ends of which are placed a vacuum-valve mand safety-valve m', respectively. From the center of said branchesleads a pipe, at the end of which is placed a pressure-gage n, the saidhead being alsa provided with a man-hole M for conveying the hops intothe extractor, said man-hole having a hinged cover-plate M', saidcover-plate being securely fastened to the man-hole when the extractoris in operation. At the center of the head S is located a bearing g,having a stuffing-box and following to prevent the escape of the solubleproducts, &c., of the hops. Within said bearing a shaft C is jcurnaled.

C is a shaft, journaled near its upper end in the bearing g and near itslower end in the bearing O of the cross-bar O, said shaft having acollar T, bearing with its lower surface against the upper surface ofthe bearing O, the purpose of this collar being to support or uphold theshaft C, said shaft having at its upper end a bevel-gear a, said gearmeshing with a bevel-pinion a', the object of which being to enable theshaft to be revolved when desired. l

C is a cross-bar having a hole through its center, said cross-bar beingadapted to fit over the shaft and to be fastened to the same.

c is an extension-bar securely fastened to the cross-bar at one end bybolts or rivets 03', While the other end is providedwith twodownwardly-pendent bars f f, said bars being fastened to the bar c bybolts or-rivets el! elli.

c is another extension-bar similar to bar c',

and also having two downwardly-pendent bars f f, fastenedto said bar cby bolts or rivets e c, said bar c being fastened to the cross-bar O atthe opposite side from the extension-bar c.

C is also a cross-bar, having two extension-bars t' t" arranged oppositeto each other, said bars having bars 1 2 3 4, said bars being centrallyfastened to the extension-bars by bolts or rivets t t t t,'onehalf ofeach bar extending above the extension-bar and the other half below,this cross-bar and attach- IOO ments being located on the shaft justbelow the cross-bar C and its attachments.

I) is a cross-bar placed below the cross-bar C on the shaft C, saidcross-bar being provided with two extension-bars j j', arranged oppositeto each other and fastened to the said cross-bar by bolts or rivets a a;cr af, said extension-bars, having upwardly-projecting bars 5 6 7 S,being fastened at their lower ends to the extensiim-bars by bolts orrivets ti i" fr" 11', the whole forming an ellieieiit paddle oragitator.

0 is a cross-bar extending across the interior of the shell and fastenedto the same by means of bolts or rivets, said bar having a bearing O atthe center for the reception of the shaft C, the object of this barbeing to provide a bearing for the shaft iii the lower end of the shell.

Il is a cross-bar placed on the shaft below the bearing O', saidcross-bar being provided with two triangular paddles, said paddles being cut out in the center, for obvious reasons, said paddles beingfastened to the said crossbar by bolts or rivets 1j y y y, the outersides of said paddles being made to conform with the shape of the innersurface of the drinn, as shown in Fig. 3.

D isa cooler for the soluble products, essences, spirits, the., from thehops, said cooler being only used when itis desired to preserve theextracts for future use, instead ot' using the saine immediately.

E is a pipe leading from the lower end of the shell A into the cooler D,said pipe having a strainer E at its head to prevent the hops fromentering the pipe.

F is a valve, which when closed turns the flow of the extracts, &c.,into the pipe G.

G is a pipe leading from the pipe E, by means of the T G', into the pipeI, said pipe G being used when it is desired to use the extracts, the.,in brewing the beer.

II is a valve, which when closed will turn the extracts into the coolerD in an obvious manner.

I .is a pipe leading from the hettoin of the extractor into theboiling-kettle K, said pipe being' used for the purpose of conveying thehops, wort, the., into the said boiling-kettle after the saniehave beenoperated upon, said pipe having` a valve I', which is closed when theextractor is iii operation, for obvious reasons, said pipe I having anaperture r for the reception of the end of the pipe G, whereby thesoluble products, dzc., of the hops are conveyed into the boiling-kettleto be mixed and boiled with the wort.

.I is a pipe leading into the upper part of the shell A, and is used forconveying the wort or water to be boiled with the hops for obtaining theextracts, tbc., of the same, said pipe being provided with a valve J',which is closed when in operation to prevent the escape of the volatileproducts, itc.

K is the boiling-kettle, (shown only in part, as it may be of anydesired. form,) in which the wort ishoiled and from which it is drawninto the extractor.

In operation, the interior of the shellbeing filled with hops, the hotwort or water is admitted into the said shell, (the latter being onlyused when it is desired to obtain the extracts, the., for future use,)whereupon the steam is admitted into the steain-clianiber R, thusboiling the hops and the wort or water, as the case maybe. The paddlesor agitators are then started, thus bringing the hops and the wort inmuch more intimate Contact, and consequently resulting in the liberationof more of the soluble products, essences, aromas, die., of the hopsthan ever before, at the same time the operation being performed in amuch more expeditious manner on account of the paddles oragitatorsrevolving, and, as hereinbefore described, bringing the hopsand wort into more intimate contact, it being al wellknown fact that thepassage of the wort through the hops dissolves all soluble salts, aswell as liberates the volatile and aromatic essences and spirits, thelatter passing through the pipe E into the pipe G, and thence into thepipe I, from whence it passes into the kettie K, while the hops andliquor pass out through the pipe I also into the kettle K, where theextracts, dsc., commingle with the wort and are boiled together previousto fermentation, the hops being led into the kettle merely forfiltering, after which they may be thrown away. 4

lVhen it is desired to obtain the extracts, the., for future use, watermay be admitted into the extractor after the saine has been filled withhops, after which the steam is admitted into the chamber R and thepaddles started as before. lVhen the extracts, soluble products, dse.,have been thoroughly liberated from the hops, the said extracts areconveyed through the pipe E into the coolerD. \Vhen the said extracts,the., are cooled, they may be drawn from the cooler by means of the pipeD.

It will now be seen that the device herein before described possessesmany decided ad vantages over any with which I ain acquainted, owing tethe fact of the revolving of the agitators or paddles hastening theliberation of the essences, aromas, the., of the hops, and consequentlyenabling the brewer to make more and better boerin less time thanbefore.

It will be further observed that this device has another advantagethatof being enabled to make the extract and cooling the same for futureuse.

Il'aving thus fully described my invention, I claim as new and desire tosecure to me by Letters Iatent of the United States* l. In aliep-extractor, the combination, with the shell A, of the pipe E,communicating with the cooler D, the valve l? in said pipe, the coolerI) and its outlet-pipe D', the pipe G, having valve Il, and connectingthe pipe E with pipe I, said pipe I and its valve I', and the kettle K,into which the pipe I dis IOO IIO
